STEAM-EXHAU ST HEAD.

SPECIFICATION forming part of ,Letters Patent No. 537,645, dated April 16, 1895.

Application filed October 10, 18 94:. Serial No. 525,457. (No model.)

To all whom, it may concern.-

Be it known that I, JUSTUS W. PARKER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful. Improvement in Steam-Exhaust Heads, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a novel construction of exhaust head, into which head exhaust steam is conducted prior to its escape into the atmosphere, whereby the noise ordinarily caused by the escape of said steam is reduced to a minimum, and provision also made for the separation of any entrained water from said exhaust by centrifugal action, and for the immediate withdrawal of said water from the aforesaid head, all as will be hereinafter set forth.

Figure 1 represents a longitudinal section of an exhaust head embodying my invention.

Fig. 2 represents a plan View of the same.

Similar letters of reference indicate corresponding parts in the two figures.

Referring to the drawings: A designates an inverted conical casing, open at each end and having secured to its smaller end, the nipple B, part of which projects upwardly into said casing, and is provided with a flange or not as desired.

D designates asuitable filling piece or wall, inserted between said nipple and easing, the same being preferably inclined and forming with the nipple and easing, a gutter O,which serves as a receptacle for the water of condensation, as will be hereinafter explained, said gutter being on a level with the bottom of the discharge opening A. of the casing A, at which opening is secured the nozzle ordri p pipe E.

WVithin the casing A above the nipple, is secured the open-ended conical shell F, the small end of said shell being above, forming a nozzle J.

G designates a curved or other shaped hood, secured to the upper portion of the aforesaid casing A, the free end H of said hood overhanging the nozzle J, a passage G existing between said end and the adjacent portion of the casing A, substantially as seen in Fig. 1.

K and L designate ports respectively at the junction of the hood G and the shell F with the casing A, which allow any water of condensation which may accumulate at either point to reach the wall D, from which it is conducted away by the gutter O to the pipe E.

The operation is as follows: The exhaust enters the lower chamber under the shell F, which is to be designed large enough to hold the cylinder exhaust at atmospheric expansion, thus preventing back pressure on the engine. The steam then escapes by passing up through the nozzle J, after leaving which it impinges on the hood G, and is deflected thereby down upon the outer wall of the shell F, at which step any entrained water will be separated by centrifugal action, the steam then escaping through the passage G to the atmosphere, while the water separated therefrom discharges through the ports K and L, and so reaches the gutter O, by which it is dirooted to the pipe E.

It will be noticed that the axes of the shell and casing are eccentric, by which provision the exhaust entering the latter will first impinge with great force upon that portion of the side of said shell directly above the nipple B, and will then contact with the overhanging portion of the hood G, the free end H thereof being preferably on a line with the left hand portion of the shell F, as seen in Fig. 1, whereby a positive centrifugal action will be given to the exhaust, as has been stated. 7

It will furthermore be apparent that a head constructed as above described in accordance with my invention is well adapted for use as a spark arrester, said head being capable of being readily attached to the smoke box of a locomotive or other engine in any desired manner as is evident.

It will be obvious that various changes may be made by those skilled in the art in the construction of the herein described head, which will come within the scope of my invention, and I do not therefore desire to be restricted to the exact structure I have herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is=- 1. An open ended tapering casing, having its largest diameter above, a tapering shell secured within said casing, having its smallest diameter above, forming a nozzle,a hood above said shell, the axes of the latter and of said casing being arranged eccentrically to each other, whereby the incoming steam first impacts on the longer portion of said shell and is deflected thence into said hood, substantially as described.

2. An exhaust head consisting of an inverted conical casing, anda conical shell and a hood therein, said hood being above said shell, and the latter over the inlet end of said casing, the axes of said casing and shell being arranged eccentrically to each other whereby the incoming steam first impacts on the longer portion of said shell, and is deflected thence into said hood, substantially as described.

3. An exhaust head consisting of an inverted conical casing, having a gutter formed by an inner inclined wall, near'the lower end of the casing, said gutter having a discharge opening, a shell secured within said casing, above said gutter said shell and easing having their axes arranged eccentrically to each other a hood supported above said shell and having a passage between its free end and said casing, and both the shell and hood having ports at their junction with the casing, said parts being combined substantially as described.

4. An exhaust head, consisting of an inverted conical casing, a nipple secured to said casing and projected into the smaller end of the latter, a filling wall between said nipple and easing, a shell forming a nozzle and secured to said casing above said nipple, and a hood in said casing above said shell, having a passage between its free end and the casing, said shell and hood having ports at their junction with the casing said shell and easing having their axes arranged eccentrically to each other, and the latter havinga discharge opening at substantially the level of the filling wall, said parts being combined substantially as described.
